No lights at all

If all light are affected, there is only one common element with them, the headlight switch. The switch is powered via a fuse. Check that first. If it is good, I suspect the switch is bad.

The fuse is in the vehicle, left side of dash. It is fuse number 14, a 15 amp fuse.

Check that first and let me know what you find.
